DEMOUNTABLE RING Filed July 27, 1956 2 Shets-Sheot 2 49 72. Q 56 i W 54Q 0 O J INVENTOR Enach- Conrad Clannarson BY M W ATTORNEYS Patented May31, 1938 UNITED STATES PATENT OFFICE Claims.

This invention relates to an improvement in rings or arenas used forboxing or wrestling exhibitions, athletic contests'and the like.

. An object of the invention is to provide a round ring which isadaptable'for boxing, wrestling and other exhibitions. w H

Anotherobject of the invention is to provide a ring which may bedismantled, transported from place toplace, and convenientlyreassembled. i

A further object of theinvention is to provide a ring in which a fairercontest may be staged and which provides a greater degree of safety forthe contestants. i The rings now in use are ordinarily built at theplace where they are intended to be used and are not easily dismantledor stored. These rings, due to their temporary nature and due to thedifficulty ,of constructing them, are square in shape, having fourcorners outlined by, ropes. In boxing and wrestling exhibitions thecontestants quite often receive serious rope burns and are often thrownfrom the ring tothe floor below,

.suffering serious injury.

- The present invention isdesigned to provide a greater margin of safetyfor the contestants and at the same time present a ring which may bedismantled or adjustedfor various purposes. The invention also presentsa ring which overcomesmany-of the disadvantages found in the rings nowin useand one which is economical and sturdy in construction.

Figure 12 is a sectional view similar in some 5 respects to Figure 2,but showing a modified means of fastening the ring members shown inFigure 4.

By referring to the drawings, it will be seen that I provide a floor |5which is built in sec- 10 'tions having an inner portion l6, a middleportion I! and an. outer portion l8. This floor is built upon aframework l9 which consists of a series of girders and posts fastened toa plurality of outer posts 20. work |9 consists of a series of girders2| running from the posts toa disc 22. The disc 22 is provided withgrooves 23, while the girders 2| are provided with books 24 which fitinto the grooves 23. A plate 25 fastens over the ends of the girders andis held in place by means of screws fastened through said plate 25 intothe disc 22 to hold them in place. The disc 22 is provided with aspindle or center post 26 which connects the disc 22 to a similar disc21. Extending from the disc 21 to the posts 20 there are girders28similar to thegirders 2|. They are similar in construction and areprovided with the hook 24 to hook'into the recesses .or grooves 29 inthe disc 21 and are held in place by the fastened to the disc 21 bymeans of screws. The length of the spindle 26 will vary in accordancewith the height of the ring. Intermediate the posts 20 andthe spindle 26there is a series of The lower part of the frame- 15 plate 30 which is30 supporting posts 3| which hold or support the ring. These posts areconnected with the girders 2| and 28 and are fastened to said girders byrivets or bolts 32. The girder 2| is fastened to the post 2|] by a boltor rivet 34 at its outer end,

the post 20 being recessed to fit over the upwardly extending flange 33of the girder 2| The girder 28 is fastened by a ring plate 35 boltedthereto by the bolts 36, as shown in Figure 5.

The girder 28 is preferably made of four angular beams bolted togetherso that the angles form a groove 31, as may be most clearly seen inFigure 12. Circular supporting members 38 extend from post to post, bothat the upper and lower sections of the frame, and are bolted thereto bythe bolts 39. The floor portions I6 and I! are grooved to cooperate withthe groove 31 formed by the flanges 40 and 4| of the beam 28, and arethus held from slipping, as shown in Figure 3. The outer floor portionsl8 are not grooved, but are made to rest upon the flange 40 and are heldin place by sunken plates 42, as shown in Figure 7. A rectangular recessis made in each floor portion l8 so that the floor portions I8 must bein correct position for the plate 42 to register. This plate is boltedto the girder 28.

In the form shown in Figures 1 and 2, shackle members 43 are fastened tothe posts 20. To these are fastened springs 44 which in turn cooperatewith shackle members 45. Circular ring members 46, preferably of steeland having angular ends 41 surrounded by a collar 48, are fastened tothe shackle 45. The ends 41 of the cir cular ring members are notched,so that a bolt or rivet 49 through the collar 48 will hold them firmly.The circular ring members 46 are covered with rubber or other flexibleresilient material 50, so that a person thrown against the ring memberswill not be burned.

In the modification shown in Fig. 12, the outer ends of the girder 28and of the floor portions I8 are provided with a groove and apulley-carrying block 52 is fastened to the post 20 immediately underthe girder. The springs 44' are not fastened directly to the shackles 45nor to the posts 20, but the posts 20 are equipped with three pulleys53, 54 and 55. These pulleys have their Wheels off-set, so as to permitthe passage of the cables 56, 5'! and 58 through the ends of theshackles 45 to the slot 5| and through the pulleys on the block 52. Inthis modification the springs 44 are fastened to shackles 59, 60 and 6|bolted to the beam 2|. Obviously, turnbuckles or other adjustable meansmay be interposed between the springs and the cables in order toincrease or lessen the tension of the springs.

When it is desired to dismantle the ring, the springs or cables areremoved from the ring members 46 and the floor plates 42 are loosenedand removed. The floor portions l6, I1 and I8 can then be slid out andremoved. The plates 25 and 30 may then be loosened and the bolts 36 and39 removed. The girders 2| and 28 can then be removed from the discs 22and 21 and from the poles 20. In this way the ring is quickly collapsedfor removal to another place and may be set up by the reversal of theprocedure outlined.

It will be understood, of course, that while I have shown six posts inthe ring, it is within the concept of the invention to increase ordecrease the numberof posts and floor sections if desired. It islikewise within the concept of the invention to make the circular ringmembers in one or more pieces and to make them of any suitable material,

although I have found steel to be the most adaptable. There areobviously many detailed parts which may be substituted withoutmaterially changing my conceptive idea.

I claim:

1. A ring including an understructure supporting a platform, saidunderstructure including a central spindle, a grooved disc at either endof said spindle, radially extending supporting members detachablyfastened to said discs and having upwardly extending posts at theirouter ends, rigid members extending between said posts, and means fordismantling said understructure and for disconnecting said radialmembers from said discs and from said rigid members.

2. A ring including an understructure supporting a platform, saidunderstructure including a central spindle having radially extendingsupporting members, said platform comprising a plurality of sections,said sections being grooved, and means on the radially extendingsupporting members to cooperate with the grooves to hold the sectionsand platform in place.

3. A ring comprising an understructure supporting a floor, ring memberssupported above said floor, said understructure having a plurality ofposts at its periphery and each of said posts having pulleys thereon,cables extending from the ring members through the pulleys, and meansfor resiliently fastening said cables to the understructure.

4. A ring comprising a supporting understructure, a floor on saidunderstructure, said floor being composed of a plurality of sections,and means on said understructure for detachably holding the floorsections in place, said means consisting of flanges on said supportingunderstructure and grooves on said floor sections, said flanges beingadapted to co-operate with said grooves to hold the floor firmly inplace.

5. A ring including an understructure supporting a platform comprising aplurality of platform members, said understructure including a centralspindle, a grooved disk at either end of said spindle, radiallyextending supporting members detachably fastened to said disks andhaving upwardly extending posts at their outer ends, rigid membersextending between said posts, flanges on the upper radially extendingsupporting members and grooves in the platform members adapted toco-operate with said flanges to hold the platform firmly in place.
